Suppress warnings on overlay fragments

Overlay fragments are traditionally named "fragment@NNN" but don't have
have a 'reg' property, amongst other differences from normal nodes.  Really
we should treat overlay fragments fundamentally differently, but for the
moment, suppress the common warnings about the fragment names with this
simple hack.
